ATIK is pleased to introduce a new motorized filter wheel, with multiple filter capability.

The ATIK EFW2 features a slick design, with a slim and lightweight profile. For example, the distance between any Atik camera and the wheel itself is 0mm, while maintaining the possibility to rotate the camera to any desired position. Total extra backfocus needed will be only 22mm.
